Starting to design out my build, looking for critique

[AndyUK]

1. I have seen that people usually use transformers for their steppers, and I understand that that is because regulated PSUs may have problems with the current spikes (at least according to the app notes). I could not find a proper post on how to do it on here though, so If anyone has a good source on that, that would be perfect.

My build thread, post number 30 has an outline of the process I followed, but I emplore you to find multiple independent sources of information and fully understand and verify before playing with a mains level PSU - this is the scary bit of the project to me, because one slip can potentially kill. Always ensure the caps discharge and never work near the PSU whilst alone in the room. I've have given the wife very clear instructions on how to isolate the supplies if it goes wrong. ALWAYS have a bleed resistor - it's not something I mentioned in my thread, but it's a must.

Scary bit over, it's not that hard or expensive. You just need to stay safe.

As for information, I didn't find a definite thread here, probably for good reasons. You're going to have to go research the theory of unregulated PSUs. Joe's videos are also quite good at explaining, and so are ThisOldTony's CNC build videos.
